4 Claims.

The invention aims to provide a new and improved device designed primarily for use by barbers to blow loose hair which has been clipped or cut off, from the necks and heads of patrons,

overcoming the necessity of using more or less ,Y

said valve whenever the trigger is pulled.

Yet another object is to provide a novel construction in which the trigger for opening the air valve is carried solely by the nozzle, whereby said nozzle and the trigger carried thereby may be quickly and easily mounted upon an air-conduct ing tube having a rearwardly opening valve, in readiness for use to open said valve when the trigger is pulled rearwardly.

A still further aim is the provision of an exceptionally simple and inexpensive construction, yet one which will be reliable, durable and in every way desirable.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to 'the accompanying drawing.

Figure 1 is a perspective view.

Figure 2 is a central vertical longitudinal sec tional view showing the air valve closed.

Figure 3 is a view similar to Fig. 2 but showing the air valve opened by a rearward pull on the trigger.

'Figure 4 is a transverse sectional view on line li-d of Fig. 2.

A preferred construction has been illustrated and will be rather specically described, with the understanding, however, that within the scope of the invention as claimed, variations may be made.

The numeral 5 on the drawing denotes a rigid tube ci metal or other preferred material, the front and rear portions 6 and 'l of said tube being disposed at an obtuse angle to each other, said rear portion 'i constituting a handle from which the front or air outlet portion Ii of the tube projects forwardly. The rear end of the tube is connectable in any preferred manner with an air hose 8 extending from any suitable source of compressed air. Within the front portion IS is a forwardly closing valve 9 which is preferably a conventional iniiation valve core.

Rigidly connected with the front end of the tube portion G, is an elongated body or nozzle Ill, the rear end of said body or nozzle being preferably provided with a socket I l into which the front end of said tube portion Sts, the two being provided with screw threads I2. The nozzle or body I 0 is provided with a longitudinal bore I3 and with a smaller air discharge bore I4, said bore I3 being provided to accommodate a portion of a valve opening trigger hereinafter described, and when this trigger is actuated to open the valve 9, compressed air is discharged through the bore I4,

The above mentioned trigger, in the present disclosure, comprises a rod I5 slidable longitudinally in the bore i3 and having its rear end in abutting relation with the valve stem i6, a pull rod Il extending longitudinally under the nozzle or body I, a U-shaped connecting portion I8 in front of the body or nozzle l0 and connecting the rods I 5 and I'l with each other, and a fingerengaging portion I9 projecting downwardly from the rear end of the rod I1, all of the portions I5, I8, I7 and I9 being preferably bent from a single piece of stiff wire or rod. The rear extremity 2i) of the rod I5 is upset somewhat in the present disclosure to prevent forward sliding of said rod from the bore I3.

The nozzle or body I0 is provided with ap propriate means to hold the entire trigger against swinging about the axis of the rod I5, said nozzle or body being preferably provided with a longitudinal groove 2l slidably receiving the rod I1, for this purpose.

.It is preferable that the nozzle 0r body I9 be substantially elliptical in transverse section and that it be reduced in size at its front end, which is particularly desirable in permitting insertion of said nozzle or body between a patrons neck and his collar to blow out loose hair.

From the foregoing taken in connection with the accompanying drawing, it will be seen that a novel device has been provided for carrying out the objects of the invention. The rear portion 'l of the tube 5 may be conveniently held in one hand and the finger-engaging portion I9 of the trigger readily pulled with one nger of the same hand whenever air is to be discharged, and by using the device to blow oif loose hair which has been clipped or cut, there is no necessity of using the old-fashioned duster which is now prohibited by lawV in a number of States, due to itsv unsanitary nature. While preferred details have been shown, at-

` Y tention is again invited to the possibility Vof making variations within the scope of the invention as claimed.

I claim:

1. A device of the class described comprising an air-conducting element, a forwardly closing valve within the front portionv of'said air--con` 10 ducting element, an' air discharge nozzle con-V nected with the front end of said air-conducting element and having a longitudinal bore, and aY valve-opening trigger slidably carried by said nozzle, said tri er com risin a valve-o enin l5 gg p g p g Y air-conducting tube, a valve opening rod slidable in said bore and projecting forwardly from said rod slidable in said bore and having its rear end disposedin abutting relation with said valve, a pull rod at the exterior of/said nozzle, a connecting portion rigidly connecting the front ends of the two rods, and a lnger-engaging portion on 20 the rear end of said pull rod, the outer side of said nozzle being provided with Ya longitudinal groove in which said pullrod is slidable.

2. `An attachment' for an air-conducting tube end; said attachment comprising an elongated air discharge nozzle having provision at its rear Yend for connecting it with the front end of the air-conducting tube, said nozzle being providedn with a longitudinalV bore, a valve opening rodf30 slidable in said borer and projecting forwardly said nozzleand having a downwardly projecting iingerpiece at its rear end by means of which it may be rearwardly slid, and a rod-connector having a rearwardly opening valve in its front *25 spaced in advance of said nozzle and rigidly connecting the front end of said pull rod with the front end of said valve opening rod, said nozzle being provided with an external longitudinal groove slidably engaged by said pull rod to hold said finger-piece properly positioned in readiness for use. f y

3. An attachment for an air-conducting tube having a threaded frontl end and a rearwardly opening valve in said frontend; said attachment comprising an elongated air discharge nozzle having a threaded sockety in its rear end and a reduced bore extending from said socket through the front end of `the nozzle, said socket being intended to receive the threaded front end oi the nozzle, the rearv end of said valve opening rod beingkdisposed in said socket and intended to abut the valve of the tube, said rear end of said valve opening rodA being provided with a stop Y Within saidsocket to prevent forward Withdrawal of the rod from said bore, a pull rod extend- Y ing along the exterior of said nozzle and having a downwardly projecting linger-piece at its rear end by means of which it may be rearwardly slid, and a rod connector spaced in advance of Asaid nozzle and rigidly connecting the front end of said pull rod with the front end of Vsaid valve opening rod, said nozzle being provided with external means slidably engaged by said pull rod to hold said nger-piece properly positioned for use. Y

4. A structure as specified in claim 3; said external means comprising a longitudinal groove in which said pull rod is slidably received to bold said linger-piece properly positioned for use.
